The draw for the Round of 32, Round of 16, Quarter-finals and Semi-finals was held on 18 October 2012 at 12:00
CEST in
La Ciudad del Fútbol in
Las Rozas,
Madrid. In this round, all
La Liga teams entered the competition. Like previous years, Round of 32 pairings was as follows: the seven remaining teams participating in
Segunda División B and
Tercera División were drawn against the
La Liga teams which qualified for European competitions, this is: four teams from Pot 1 (Segunda B) were drawn against four teams from pot 2a (champions) and the three remaining teams in pot 1 were drawn in the same way with the pot 2b teams (Europa League). The five teams in Pot 3 (
Segunda División) were drawn against five teams of the thirteen remaining teams of La Liga (Pot 4). The remaining eight teams of La Liga faced each other. Matches involving teams with different league tiers played at home on the first leg the team in lower tier, in the other matches the first team to come out of the draw played at home. This rule was also applied in Round of 16, but not for Quarter-finals and Semi-finals, which order of legs was pure as of the order of draw. At the time of the draw, the result of the match between Las Palmas and Racing de Santander (which was played later that day) was not known.
